FlagQuantum Compiler QSteed v0.2.0

Highlights

• One-command installation from PyPI: pip install flagquantum-compiler-qsteed==0.2.0
• Vendors the minimal QSteed compiler core under a private namespace
• Removes the external QSteed, QuarkCircuit, QuarkStudio, database, and service installation path
• Supports FlagQuantum 0.2 and later
• Verified on Python 3.10, 3.11, and 3.12 against FlagQuantum 0.2.0 and current main
• Preserves the upstream Apache-2.0 license, source commit, and modification record

The release workflow builds and validates one wheel and one source archive, publishes those exact artifacts to PyPI through Trusted Publishing, and attaches them to this GitHub Release.
